Ventilator fan for water closets



June 7 1932. J. "HERTZOG VENTILATOR FAN FOR WATER CLOSET S Filed Jan. 29, 193} Patented June 7, 1932 30m: nanrzoe, or nonam, onro PATENT OFFICE vmmuron IAN FOR ATER CLOSETS Application filed January 29, 1981. Serial No.'512,190.

My invention is an improvement in ventilators .for water closets, and relates more especially to apparatus for attachment to the bowl for the purpose of withdrawing obnoxious odors and discharging them into the outer atmosphere so as to maintain a sanitary condition in the room in which the water closet is located.

7 The primary object of my invention is to provide an apparatus of this eneral character which may be readily app led to any conventional type of water closet bowl by an unskilled mechanic, the suction'pipe through which the odors from the bowl are drawn being secured in place by means of the hinges connecting the seat and lid to the bowl.

A further object of my invention is to provide an apparatus of this character which is adaptable or application to different types :0 of water closets with either high or low flushing tanks, the construction of the suction pipes which are attached to the bowl'beingv such that the suction fan and motor for operating-the same may be located in the rear of the water closet bowl or at either side thereof whichever is more convenient.

My invention also contemplates a constructionof the arts constituting the ventilating apparatus or water closets by which pro- 80 vision is made for certain adjustments with respect to the hei ht of thebowl and location of the rforate suction pipe beneath the seat; a as hereinafter in] y described and specificall set forth in the appended claims.

' In the rawing: 4 .Fi re 1 is a side'elevation illustrating the apphcation of my invention, the suction fan and motor being located at one side of a low.

flushing tank.

Fi 2 is 9. Ian view of Fig. 1 with the flushing tank indicated in dotted lines.

Fi 8 is a detail planview of the suction cham r located below the seat of the closet. Fig. 4 is a front elevation thereof, and

W ration I-haveshown in the drawing that Fi 5 is a sectional view of the suction i form comprising a bowl 10, on which the seat 11 andlid 12 are hinged at their rear ends by means of spaced apart posts 13, 13 to which the hinge-leaves 14, 14 and I5, 15 for the seat and lid respectively are pivotally connected, the lower ends of said posts below the collars passing through a rearward extension 16 of the bowl and threaded at'their ends to receive the clamping nuts 17, with the water supply pipe 18 from the flushing tank 19 discharging into the upper part of the bowl at the rear end thereof. In the construction of water closets of this type it is usual to leave a space between the seat and top of the bowl, the forward end of the seat opposite the hinges being supported by rubber blocks 20, and in order that my improved ventilating apparatus maybe applied without altering the water closet one part of the apparatus or attachment is inserted between the seat and bowl and held in place by the hinge posts and extends beyond the water closet in the rear thereof for connection with the motor-driven suction fan.

, In carrying out my invention I provide a suction chamber 21 into which the obnoxious odors from the bowl are drawn, the front end of said chamber which fits between the closed lid 12 and bowl 10 being flat to accommodate the usual space which is left between these parts of the water closet while the rear endof said chamber is tubular to receive an outlet or discharge pipe 22 at either end thereof. This suction chamber is constructed of a plate bent uponitself to provide'a tubular rear end 23 from the lower portion of which themembers of the plate extend forwardly and are separated by metal strips 24, 24 at opposite sides with additional U-shaped spacing strips 25, 25 around cutouts 26, 26 at the front end to receive the hinge-posts 13, 13, with the front end of the suction chamber extended as shown in Fig. 3

to correspond approximately with the shape of the seat under which it projects as shown in Fig. 2, the aforesaid spacing strips being riveted to the upper. and lower members of.

the bent plate. Both ends of the tubular por- I tion23 extending across the rear 'end of the suction chamber are left open to receive the outlet or discharge pipe into either end therely at their lower ends to bear upon the dis charge pipe 18 of the water closet bowl with 'a metal strap extending around said discharge pipe and connected at its ends to the aforesaid brackets.

The discharge pipe from the suction chamber is connected to an inlet pipe 28 leading into a conventional type of suction fan 29 driven by an electric motor 30, the suction fan discharging into a pipe 31 connected to a stack (not shown) or extending through a wall of the room in which the water closet is located for discharging the obnoxious odors directly into the outside atmosphere, and for controlling the operation of the electric motor which drives the fan an ordinary form of switch 334is employed and conveniently located as for instance at one end of the flushing tank. The combined fan and motor may be supported on a bracket 32 as shown in the drawing so as to be located at one side of a low flushing tank, or supported on a stand (not shown) located at any convenient place, as for instance directly in the rear of the bowl or at either side thereof.

In applying the apparatus to awaterstrips 25, 25 so that when the nuts 18 are threaded on the lowerends ofthe hinge-posts said suction'chamber will be tightly clamped on the bowl, any required adjustment with respect to the bowl being permitted by reasonof the cut-outs. The support, as'bracket 32, for the combined fan and motor, is then secured in place on the wall and after mounting the combined suction fan and motor on the bracket the suction chamber is connected to the fan by pipe 22 and the outlet from the fan connected by pipes to the outside atmoshere, the said suction chamber being further eld against displacement by the strap 35. It will thus be seen that the installation may beeasily accomplished by an unskilled person'to not require the services of a plumber inasmuch as no part of the plumbing is disinstalled by the owner of a house, the adjustability of certain parts accommodating the ventilating apparatus to water closets of different types as to hei ht, etc.

It will be understood t at changes or modifications may be made in the essential parts constituting my invention, as for instance the shape of the suction chamber may be altered to suit different conditions-with respect to the water closet fixtures, and instead of mounting the fan and its driving motor on a wall bracket it is obvious that where? conditions require an adustable stand shown) may be employe to rest on'the adjoining the water closet.

I claim 1. A suction'chamber for ventilating apparatus for water closets, to fit across the the tubular portion and open at its forward end with the front ends of the members out back and having cut-outs near the opposite ends thereof to receive the hinge posts and strips reinforcin the cut-outs around the edges thereof, said strips providing central 1 and side inlet openings to the aforesaid passage.

2. A suction chamber for ventilating apparatus for water closets comprising a plate bent upon itself to provide a tubular portion at the rear end ofthe chamber with the members of the plate extended forwardly and separated by strips to form a .flat shallow passage with cut-outs at the forward end thereof, stri s reinforcing the cut-outs around the e cured to the underside of the suction chamber near the rear end thereof, and a metal strap attached to said brackets.
